Siemens S7-300 PLC Programming cable,5 meters.
PC / MPI adapter is also known as PC adapter. It’s physical interface is the
conversion from RS232 interfaces to the RS485,including the conversion from
RS232 to MPI protocol (MultiPoint Interface).And it is used for the connecting
between the PC COM (RS232) and MPI (RS485) of Siemens S7-300PLC.This product is
non-isolate, choose PC / MPI + if you need an electro-optical isolation.
Main technical parameters：
★ RS232 Port baud rate：19.2Kbps
★ MPI Port baud rate：187.5Kbps
★ With the data received and sent indicator light
★ Temperature：0～75℃
★ Total length of cable：5m
STEP7 Software settings：
1、 Go into STEP7 the main software programming interface（SIMATIC
Manager），click “Set PG/PC Interface…” which is under the “Options” menu, and the
get to the PG/PC setting interface。
2、 Double-click on “PC Adapter（Auto）”or“PC Adapter（MPI）”to go into the
interface setting of parameters of RS232 and the MPI. The adapter does not
support "PC Adapter (PROFIBUS)" option.
3、 Click on the "Local Connection" option to set the interface parameters of
RS232, to choose the right computers COM mouth (RS232), change the RS232
communication baud rate to 19200 bps.
4、 Click the "MPI" option (if it's on "PC Adapter (MPI)" method) to set MPI
interface parameters for the adapter, as the MPI interface of the adapter gets
the baud rate fixed at 187.5 Kbps, so here can only be set to 187.5 Kbps.
If
it is "PC Adapter (Auto)" method the choice should be "Address: 0" and "Timeout:
30s".
After the settings above the adapter can be set up on-line communication
with the PLC, now you should pay attention to that you shouldn’t change the
factory default of the MPI port baud rate 187.5Kpbs on the CPU which is under
the “Network Settings”.
Since the baud rate of the MPI port of the adapter is fixed at 187.5Kbps,
if it is set at other figures, the adapter will not work with PLC! Make sure
that the baud rate of the MPI port on your S7-300PLC’s CPU is fixed at
187.5Kpbs.Otherwise,you have to use the Siemens's programming communication
facility to set that baud rate to 187.5Kpbs,in order to make the adapter work
correctly.
Not isolated,so it doesn't support hot plug,if need isolated cable,pls
